Abstract

Congenital heart disease is generally evaluated with the use of echocardiography. Transthoracic echocardiography image quality may be suboptimal due to poor acoustic window with limited depiction of extracardiac vascular structures. Catheter angiography produces overlapping views of adjacent vascular structures, causing difficulty in the simultaneous depiction of the systemic and pulmonary vascular systems, leads to undesirable catheter-related sequelae (vascular injury), and delivers relatively high doses of ionizing radiation. Even though magnetic resonance imaging (MRI) is eminently capable in the anatomic and functional evaluation of the heart, it is time-consuming and often requires lengthy sedation; therefore, the use of MRI in seriously ill newborns or young infants is usually restricted. Cardiac computed tomography (CT) is the preferred imaging modality for evaluation of young infants with coronary anomaly, major aortopulmonary collaterals or airway issues. Cardiac CT gives superior image quality for three-dimensional modeling and image fusion with fluoroscopy or merged to electroanatomic mapping to precisely visualize complex anatomy and guide intervention.
